sTomaPaoF ROLLER CURTAIN ATTOR NEY Patented Dec. 3, 1929 CLARENCE H. MEADER, OF ST. PAUL,` MINNESOTA STORMPROOF ROLLER CURTAIN Application filed March 23, 1928. Serial '.N'o. 264,104.

This invention relates to improvements in curtains especially adapted tor use upon locomotives, automobiles, etc., and has lor an object the provision of a storm proof curtain which may be readilj7 adjusted for use, or positioned within a protective housing when not in use, the housing also protecting the curtain roller at all times.

Another object of the invention is the provision of a housing for this purpose which is of novel construction and within which the curtain may be mounted so that it may be readily withdrawn, yieldable means being provided to closely engage the curtain at all l5 times to exclude rain and snow, yet permit ol the ready manipulation of the curtain.

Another object of the invention is the provision oi' a spring roller curtain and housing therefor having means upon the outside o'l the housing for adjusting the tension of the roller spring.

In the drawings Figure 1 is an elevation illustrating the curtain arranged for use in the window of a locomotive cab.

Figure 2 is an enlarged sectional viewon the line 2-2 of Figure 1.

Figures 3 and 4; are fragmentary sections taken respectively on the lines 3-3 and ln-Ll of Figure 1, the views being on an enlarged scale.

Figure 5 is a section on the line 5-5 of Figure 3.

Figure 6 is an elevation showing a portion of the body of an automobile with the inven` tion applied.

Figure 7 is a fragmentary sectional view on an enlarged scale, the section being taken on the line 7-7 of Figure 6.`

Figure 8 is a detail perspective view ot the curtain housing shown in Figure 7.

Referring to the drawings in detail wherein like characters of reference denote corresponding parts, the reference character 10 4:5 indicates a window frame which may represent the frame of a window of a locomotive cab. The invention which is designed to close the window opening includes housings 11, one of which is positioned at each side of the window. These housings are of like construction and each includes an attaching bracket 12 and 'a rib 13, the latter extending from one edge of the housing. The housing is elongated in shape and has one of its laces open and while the housing is shown as being cross sectionally rectangular, thisparticular shape is not essential.

The open face of the housing is closed by a closure memberll, This member is cross sectionally semi-circular or substantially so, and entends longitudinally oi the housing 11 with its ends closed by disk-like heads 15. A flange 16 extends longitudinally along `one edge olf the `closure member 14 adjacent the rib 13 of the housing. j

Mounted for axial rotation within the housing between the heads iZ the closure member is a spring influenced roller 17. The lower end of this roller carries a trunnion 18 which is rotatable in a bearing provided in 79 the end of the housing 11 and in the adjacent disk 15. The opposite end of the roller has mounted therein a spring 19 which has one ci its ends secured to the roller and its opposite end secured to abar 20 j nojecting from the endof the roller 17. This bar is engaged by the bifurca-ted end of a screw 21 which is adjustable in the housing 1l and which is held in adjusted position by means of lock nuts 22. A curtain 23 is wound upon 130 the roller 17. A spring 2li which has one of its ends secured to the housing and its 0pposite end to the closure member la as shown in Figure 5 of the drawings, acts to yieldingly hold the member 14 in position to close thc housing and to yieldingly contact with the curtain as the latter is withdrawn lrom or wound within the housing, the curtain however having ree movement.

The free end of the curtain is provided'@ with a strip 25 of suitable material and these free curtain ends are adapted to overlap and be secured together as shown in Figures 1 and 2 of the drawings so as to close the window opening. By 'reason of the character and manner of controlling the closure inember 14, this member will sufficiently close the housing as to protect the curtain and the curtain roller at all times. j

In Figures 6, 7 and 8 of the drawings, the

invention is. shown as applied to an antoniobile. In this form of the invention, the curtain roller 26 is horizontally arranged and the curtain 27 ma be provided With transparent panels any with a normally closed flap 28 so that When the free edge of the cur vtain is secured to the body of the vehicle as shown at 29, the flap 28 will permit of the v hand being extended for signalling purposes. The roller 26 is mounted for rotation Within a housing 30 and this housing is provided lWith an attaching flange 31 which is secured along the top 32 of the automobile. The housing is provided along one edge With a Y Vflange 33 Which extends oppositely from the flange 31,. Mounted for axial rotation Within the vhousing 30 is a `transversely curved closure member 34; `from which the curtain `27 extends, the'closure member 34 being pro* 20 vided Ywith a flange 35 over which the cur tain passes. g f

The invention is susceptible of various changes in its form, proportions and minor details of construction and theright is herein reserved to' make such changes as properly fall within the scope of the appended claim. p yHaving described the Yinvention what is claimed is Y 4 e In a curtain mounting, anelongated housing, a hollow substantially cylindrical closure member having a disk at each end Vthereof and. mounted for rotary movement Within the housing,vsaid member having an elongated opening therein, a ange extend- 35 ing valong one edge of the opening, a springV y influenced'roller mounted for rotation Withinthe hollowcylindrical member, a curtain Wound upon the roller and extending throughvthe housing, and'spring means to Y ,l0 yieldingly hold the flanged end of the closure member in contact With'the curtain.

In testimon whereof I affix my signature.
